31、TED VOLTAGES UP TO AND INCLUDING 450/750 V Part 1: General requirements FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote inter
32、national co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafte
33、r referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also partici
34、pate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an i
35、nternational consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all re
36、asonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply
37、IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of con
38、formity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this public
39、ation. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, o
40、r for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the corre
41、ct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62821-1 has been prepared by
42、 IEC technical committee 20: Electric cables. The text of this standard is based on the following documents: FDIS Report on voting 20/1555/FDIS 20/1567/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

44、ing 450/750 V, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication wi
45、ll be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 IEC 62821-1:2015 IEC 2015 ELECTRIC CABLES HALOGEN-FREE, LOW SMOKE, THERMOPLASTIC INSULATED AND SHEATHED CABLES OF RATED VOLTAGES UP TO AND INCLUDING 450/750 V Part 1: General requirements 1 Scope This part of IEC 62821 applie
46、s to cables with insulation, and sheath if any, based on halogen- free, thermoplastic compound, and having low emission of smoke and corrosive gases when exposed to fire, of rated voltages U 0 /U up to and including 450/750 V used in power installations of nominal voltage not exceeding 450/750 V a.c
47、. NOTE For some types of flexible cable the term “cord“ is used. The particular types of flexible cables are specified in IEC 62821-3. The code designations of these types of cables are given in Annex A. The test methods specified in this standard and in IEC 62821-3 are given in IEC 60227-2, IEC 603
48、32-1-2, IEC 60684-2, IEC 60754-1 and IEC 60754-2, and in the relevant parts of IEC 60811, and in IEC 61034-2 and in IEC 62821-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated refer
49、ences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
